PROBLEM TO BE SOLVED: To provide a condenser for florescent lamp abnormality detecting apparatus that can be easily mounted and has a high reliability. SOLUTION: This apparatus detects light from a condenser 21 fitted into a fluorescent lamp 1 and detects the abnormality of the fluorescent lamp. It comprises a fitted part 22 consisting of elastic materials in the form of string and a light introducing part 23, wherein the fitting part is not only curved along the shape corresponding to the cross section shape of the fluorescent lamp but also a portion of the fitted part is opened, thereby revealing C shape, and wherein the light introducing part is integrally formed with the fitted part so that it can be continuously protruded outside from a portion of the fitted part. The light introducing part is mounted with an optical fiber attaching aperture 25 for attaching an optical fiber 26 in the form of straight line to be penetrated in to the fitted part from its outside, wherein the shape of the aperture is tapered from the outside of the light introducing part toward the fitted part. Accordingly, the insertion and fixing of the optical fiber is easily done and there is no risk that materials blocking light such as dust can be infiltrated between the attaching aperture and the fluorescent lamp. |
